| 摘 要： | 土壤可蚀性因子K值表示土壤被冲蚀的难易程度，是影响土壤流失量的内在因素。用ArcGIS软件处理得到洛宁县土壤类型图，运用EPIC模型中的K值计算方法，根据土壤机械组成计算得出洛宁县各种土壤的K值并生成K值图。结果显示：①洛宁县土壤中不易蚀土占全县总面积的59．18％，在山地区呈“箕”形分布；较易蚀土占全县总面积的35．44％，多分布在森林覆盖率低的农垦区，比较容易导致土壤侵蚀。②土壤可蚀性因子K值代表了土壤抵抗水蚀能力的大小，与土壤的抗冲抗蚀能力呈负相关关系，是土壤侵蚀模数定量研究的重要因子。

| Abstract: | The soil erodibility factor K stood for the difficulty degree of the soil erosion,which was the intrinsic factor of the soil loss quantity.Using the ArcGIS,the soil map of Luoning County was obtained,the K computational method in the model of EPIC was applied,received the K value and the K value chart of all kinds of soil of Luoning County according to the soil mechanical composition.The results showed that the eroded soil accounts for the total soil area 59.18%in the Luoning County,and it presentedjishaped... |
